Monolithic vs. MicroKernelized• Monolithic hypervisor
– Simpler than a modern kernel, but still complex
– Contains its own drivers model
• Microkernelized hypervisor– Simple partitioning functionality– Increase reliability and minimize TCB– No third-party code– Drivers run within guests

Storage OptionsVirtual Hard Disk
Supports both Synthetic and Emulated devicesThree Types VHD file formats:
FixedDynamicDifferencing
Supports Pass-Thru disk Attaching to raw physical disk or LUNHigh performance and larger storage (beyond 2TB VHD file limit)
Disk Access Options: IDE, SCSI, ISCSIOnly can boot from IDE disk ISCSI4 IDE Disks and 256 SCSI Disks

Other Performance Tuning Options to Consider
Processor: Larger processor cache is better.
Memory: The quantity of RAM is a more important factor than RAM speed or latency.
Network:Use multiple NICs and multi-port NICs on each host server.Dedicate one NIC/Port on each host server for network I/O and management of the host itself and do not create a virtual switch using that NIC.Dedicate one NIC/Port on each host server to the private (heartbeat) network if the host is part of a server cluster.Dedicate at least two NICs/Ports on each host server to the iSCSI network if an iSCSI storage architecture is being utilized.Dedicate at least one NIC/Port on each host server for guest virtual machine network I/O. For maximum consolidation ration, utilize one or more 10-Gigabit Ethernet NICs to virtual machine network I/O.
Storage:If direct attached storage is being utilized, a SATA II or SAS RAID controller internal to the server is recommended as previously discussed. If a storage array and SAN are being utilized, host bus adapters (HBAs) are required in the host server.Periodically defragmenting, pre-compacting, and compacting the VHD files on the guest and defragmenting the volumes on the host will help ensure optimal disk I/O performance.
